Boot upper side surface



The sole FIGURE is a front elevational view of a boot upper side surface, showing my new design.

The broken lines shown on the bow are intended to disclaim the interior portions of the bow, and the broken lines illustrating the boot are solely for the purpose of illustrating context, environment or other unclaimed areas and form no part of the claimed design. 

CLAIM The ornamental design for a boot upper side surface, as shown and described.
